This invention relates generally to containers and more particularly toan improved method for assembling a multi-compartme-nted containerblank.

A primary object of the present invention is to provide a novel methodfor assembling a one-piece container blank which is readily produced andwhich includes panels which during assembly will dispose anintermediate, compartment-forming partition in its oriented position toform a multi-compartrnented container.

Another object of the present invention is to provide a novel method forerecting a container blank which automatically orients a partition toform a rnulti-compartmented container.

A further object of the present invention is to provide a novel methodfor producing a carton from a one-piece blank in which during assembly apartition panel is provided to form a multi-compartmented carton, andthe partition panel prevents bulging of opposed side walls to which itis attached.

Other and more specific objects and the nature and advantages of thepresent invention will become apparent from a consideration of thespecification when taken in conjunction with the accompanying drawing,in which:

FIG. 1 is a plan view of the blank of the invention, showing in phantomlines a glue strip area and out line for forming partition-panel andcontainer glue flaps;

FIG. 2 is an end elevation of the blank of FIG. 1 looking at the loweredge thereof, and showing in phantom lines means for applying a gluestrip to one partitionpanel-glue fiap;

FIG. 3 is a fragmentary plan view of the carton blank of FIG. 1 showingthe first fold made during assembly of the container, and showing gluestrip applied to opposite sides of the blank on the container glue flapand other partition panel glue flap;

FIG. 4 is an end elevation of FIG. 3 showing how the glue strips and acut is made between the container glue flap and the glue flap of FIGS. 1and 2;

FIG. 5 is an end elevation of the completely assembled container in itsfolded condition;

FIG. 6 is a view similar to FIG. 5 showing the assembled containerpartially erected; and

FIG. 7 is a top plan view of the erected container.

Referring to the drawings in detail in FIG. 1 a planar blank isindicated generally at 10, the blank being produced from a suitablepaperboard material or the like by die cutting, for example.

The blank 10 includes two pairs of alternately disposed rectangular sidewall panels 12, 14 and 16, 18 which are connected at the side edgesthereof by mutually parallel fold lines 20, 22 and 24. The container tobe produced from the blank of the exemplary embodiment will berelatively narrow in width, for example, the type used for pancakeflour, etc.

The sidewall panels 12, 14 and 16, 18 include at the upper and lowermargins 26 and 28, respectively, pairs of upper closure flaps 30, 32 and34, 36 and lower closure flaps 30', 32' and 34', 36'.

3,185,647 Patented May 25, 1965 The sidewall dimensions, it will beunderstood by those skilled in the art, may be varied, i.e., the sidewalls may all be of the same area.

Foldably secured at the side edge markin 38 of the sidewall panel 13 isone side edge of a first panel 40 from which will be ultimately cut atline 42 to form adjacent side edges of a container glue flap 44 and afirst partitionpanel glue-flap 46. The first partition panel glue-flapis foldably connected at its other side edge to a fold line 48;conveniently perforated if desired, to one side edge of a partitionpanel 50. The other side edge 52 of the par-tition panel 50 is connectedby a fold line to a second partition panel glue flap 54.

The width A of the first pair of side wall panels 12, 14 is equal andthe width B of the second pair of side wall panels 16, 18 is equal. Thewidth B of the partition panel 50 is at least equal to that of the sideWall panels 16 and 18. Further, the width C of the glue flaps 46, 54 isequal, accordingly the width D of the panel 40 is greater than the widthC of glue flaps 46, 54 to form a width E of the container glue fiap 44after the glue flap 46 is formed. Although the disclosed embodimentshows glue flaps 46, 54 as being of equal width, it will be readilyrecognized by those skilled in the art that the widths of the glue flapsmay be different, the prime requisite being that they be wide enough toreceive a glue strip and adhere to the opposed side walls.

The blank 16 is conveyed through suitable assembling apparatus,pertinent portions being shown diagrammatically in FIGS. 2 and 4. Theinner surface of the blank 10 is shown in FIG. 1, and the blank isconveyed beneath a glue wheel 56 to apply on the inner surface of glueflap 46 a glue strip 58. The glue strip 58 will adhere at 66 on anintermediate portion of the side Wall panel 14 when the first assemblytold is made at fold line 24; see FIGS. 2-4.

The first fold of the blank disposes, as seen in FIGS. 3 and 4, the sidewall panel 18 in overlying relation to a portion of the side wall panel14.

The blank '16 is conveyed beneath a combined cutting-\an-d-glue-applying wheel 62 which forms the out line 42 to separate thecontainer glue flap 44 from the first partition panel glue flap 46.Since the previously glued strip 58 will adhere :at 61) on the panel 14the panel 50 and glue flaps 46, 54 will remain relatively stable on thepanel 14. The wheel 62 will apply a glue strip 64 on the outer surfaceof the container glue flap 44. A glue wheel 66 will apply on the outersurface of the partition panel glue flap 54 a glue strip 68.

The next told is made at fold line 21 and the side wall panel 12 willadhere to the glue strip 68 and the portion thereof adjacent the margin70 will adhere to glue strip 64. When the container is erected in themanner shown in FIG. 6, the side wall panels 16 and 18 will swing inparallel relation about fold lines 20, 22 and 24, 38, respectively, andthe partition panel 50 will be disposed parallel to panels 16 and 18swinging about fold lines 48, 52 at the respective partition glue flaps46, 54 secured on opposed inner surfiaces of side wall panels 14 and 12,respectively,

As clearly seen in FIG. 7, when the side Walls 12, 14 are parallel toeach other, the side Walls 16 and 18 will be disposed at right angles tothe walls 12, 14 and parallel to partition 56 to form adjacentcompartments X [and Y in the erected container.

It will be noted that the blank 11) is substantially rectangular, thusthere is practically no waste of material; the assembly of the containerpositively orients the partition panel 51) to form the compartments Xand Y; the glue strips 58, 64 and 68 can be readily applied 3 withoutrequiring experience and involved apparatus and the out line 46 isreadily joined.

It will be obvious to those skilled in the art that various changes maybe made Without departing from the spirit of the invention and thereforethe invention'is not limited to what is shown in the drawings anddescribed in the specification but only as set forth in the appendedclaim.

We claim:
